I have the same problem. I don't know how to add friends to my friends list. I ask for lives and maybe get one every once in a while playing. Someone please enlighten me! Thank you!

When you play Kingdom connected on mobile a randomly group of players show up in your game. If you want to add further players that also have a King account, then open the game on King.com on a computer: https://king.com/play/papapearThen scroll down in the left column and add your friend(s) under "Add to favorites" with the email address of your friend's King account. Restart the game on mobile and your friends should show up.
